Best caliber for deer out to 800 yards

This will all come down to ones opinion. I shoot 165 grain Sierra spitzer boat tails (game kings)outta my 300 win mag. And have had great results on deer and elk both. Mine shoots about 3240 fps at the muzzle.

I kind of went thru the same search and am currently waiting for my new gun to be finished. I already had a 300wsm for elk, so I was looking for a primary deer rifle. I havent seen many people on this site like the caliber, but I ended up going with the 6.5 creedmoor. The ballistics were better than the 25-06 I was looking at. Yes there are other 6.5's out there, but with barrel life, quality factory ammo and components for reloading that are fairly easy to get, it seemed like a good choice.

Your criteria for game is identical to mine. While my typical long range shot averages 500-600 yards, I've shot several deer over 800 yards, longest 998. Coyotes out to as'far as I can range them. I switched from the magnums to the 6.5x284 several years ago for this kind of shooting. Besides beng extremely accurate, and having sufficient energy to kill deer at 1000 yards, the light recoil in a comparably lighter/shootable rig than the magnums has been more amenable for this kind of hunting for me. My 10.5 pound Cooper can be carried all day and still provide a stable platform to make consistent long range shots. IMHO.

If you want a shorter action, the .300 WSM is also a good choice.
***as is the 270WSM***

If you were to remove the limits on caliber of choice I would have included the .264 Win mag. **(.264) That is a 6.5** American vs Canadian math. Kinda like 7mm/.284 or 7.62/.308 or 6.8/.277 or 5.56/.223 etc.

The two I use most frequent for that exact purpose are the 270WSM shoving 140Accubonds at 3100(factory Win-70 fwt) & my custom Win-70, 300WSM shoving 180Accubonds at 3100+
